The invention relates to shock-formingmas chines of the general type shownin my U. S. Patents 1,295,271 of February 2 5,1919, 1,413,- 966 of April 25, 1922, 1,640,598 ofAugust 30,

In the prior machines, a rotarytablezhas been mounted upon a port-able frame to support the shock while itis being formed and torotate said shock, a cylindrical receiver has been provided above the table andin axial alinement therewith to retain the shock while it is being formed, and provision has been made for rearwardlyshifting the receiver to force acompletedshock from the rotary table, said receiver having a rearwardly'swingable gatesection which opens'to allow; discharge;

of the shocln The rotary tablehas necessa+ rily been located rather close to'theground, that the prior machines would tions inthefield. It has therefore beenthe principal object of the present invention to improve upon the prior structures by mounting the shock-supporting table and the shockforming receiver upon adrop frame, which frame is normally raised quite a distance has been foundthat when the stems above the ground,'butis lowered whenever a shock is to be discharged." Hence, the machine will more readily clear field obstructions and the operator may easily spot an areaj substantially free from such obstructions upon which to shock.

-Another object of thepresent invention has beento improveupon the means heretofore provided for finishing the .crown of the shocks. Previously, aroller disposed substantially radially of the receiver, at the up.-

per end of the latter, has beenthesole 'provi-.

for finishing the shock crowns, but it or, stalks sion 1 V of the grain are unusually long, difiiculty 1- ill be encountered in properly crowning the shocks. Such difliculty however is overcome by severing the stems and order to acco me plish this end, I. place a continuous knife upon the above-mentioned roller.

' tVith the foregomg 1n v1ew,'the invention resi c es in the novel subject matter hereinafter described and claimed, description being acd ischarge any: completed complishedhy reference to the accompanying drawings.

In the drawings above one illustrative construction has been shown briefly described,

and will be rather specifically explained, with the understanding however thatwithin the scope'of the invention as claimed, numerous variations maybe made.

M denotes a main horizontal frame having ground wheelsW and W at its rear end. but intended at its front. end (not shown) for connection with a tractor. The wheels W and W are mounted onthe/alined ends 10 and 1-1 ofa cranked axle-12,-said ends being tnrnable in bearings 13ca'rriedby the frame H M. This frame, in the present disclosure, em-

bodies two longitudinal bars 14 and '15 disposedat the'inner. sides of the wheels W" and W, respectively,-and a thirdlongitudinal bar 16 disposed at theouter side ofthe wheel-W, the rear endsof said barscarrying the bearings, 13. The front portions ,ofthese bars "14,15 and 16 maybe rigidly connectedwith .each other in any desired way'and I have shown them tied together by transverse mom-,1 I

bers 17 and 18. Rigid, rearw ardly projecting arms 19are shown secured to the member 17; and projectingrearwardl from the latter,

and. two hangers 20; are pivoted atw21 to, the

down-turned ends 19 of said arms. A horizontal drop frame D under the main frame M, is pivoted at its front end to the lower ends of thehangers 20, as indicated at 22, the rear portion of said drop frame being provided with bear ngs 23 through which the depressed central portion of the cranked with an a re riate aart of the main frame M. hen this latch means 25 is released, for instance, by a pull rod 27, the frame D descends to a rear lowered positi'on'as seen in. Fig. 2, the rearward movement of said frame being limited by any desired means such as a stop rod 28. Preferably, movement of the frame D to its lowered position, is cushioned by an appropriate shock-absorbing spring For illustrative purposes, the drop frame D is shownas embodyingparallel longitudinal side bars connected at intervals by transverse members 31. .Between the side bars 3O, is a rotatableshock-supporting table 32, said table havingascentral bearing 33 and resting near its periphery upon rollers such as 34 and 35 (see-Fig; The roller 35 is carried by a shaft 36 rotatable in a bearing 37 on one of the side bars 30, said shaft having a sprocket 38 engaging a sprocket chain 39. This chain also engages another sprocket 40 which rotates bodily with a third sprocket 41,-thetwo sprockets 40 and 41 being carried by a radius link 42 pi'votedupon the shaft 36. A driving'chain 43 engages the sprocket 41 and a sprocket 44, the latter being loose upon a short transverse shaft 45' which is mounted in appropriate bearings 46 on the bars 15 and 16 of the main frame M. Another radius link '47 is pivoted upon shaft 45 and carries the shaft,

or the like of the sprockets 40 and 41. Shaft 45 is constantly driven by a chain 48 and sprockets 4950 from the wheel W which constitutes a bull wheel for the machine. By means of an appropriate clutch 51, the sprocket 44 may be connected with the shaft 45, to drive the 'chain43, the sprockets 40 and 41, the chain 39, the sprocket 38, the shaft 36and the roller 35-, for the purpose of rotating the table 32. Such rotation of the table is effected continuously while for1ninga shock but is preferably discontinued when forcing a shock from the table. The

driving means for the table, it will be observed, is of such nature that it will not interfere with raising and'lowering of the drop frame D, attention being here invited to the differences in the positions of the radius links 42 and 47, in Figs. 1 and 2.

Two rigid vertical side frames 5 2 are carried by the drop frame D. For illustrative purposes, each of these side frames'is shown as embodying a front vertical bar 53, an intermediate relatively tall vertical bar 54, and a rearbar 55, the upper portions of thethrcc bars being secured to a horizontal longitudinal track 56. Rollers 57 engage the lower ed es of the two bars 56 and other rollers 58 b L 1 .engage the upper edges of the bars 30, tnese slides upwardly and swings rearwardly in thesame manner as in Patents 1,413,966 and 1,640,598, above mentioned, allowing the receiver to clear the shock. Before the receiver is rearwardlyshifted, in the improved machine, the drop frame D carrying said receiver and the table 32, is allowed to, lower to'the position .shownin Fig. 2, placing the shock muchnearer the ground so that there is no danger of disrupting it asit is pushed from'the table. Lowering of the frame D takes place by gravity in the present disclosure and occurs immediately upon release of the latch means 25, and unique provision is made whereby said drop frame is restored to its raised forward positionafter the shock has been discharged;

' Two unloading chains 64 extend longitudinally of the main frame M and are carried by" the latter, said chains being trained around front and rear sprockets 65 and 66, the rear sprockets 66 being rotatably supported by appropriate brackets or the like 67 carried by the bars 14 and 15, while the front sprockets. 66 are secured upon short transverse shafts. 68 mounted in appropriate bearings 69 secured to said bars 14 and 15. By means of intermeshing spur gears 70, the shafts 68 are operatively connected with a transverse shaft 71 which may be driven by a chain 72 and sprockets, from-the shaft The driving sprocket 7 3 fort-he chain 72, is loose upon the shaft 45 but may be connected with the latter by an appropriate clutch 74. This clutch and the clutch 51 are of course manually controlled.

Two longitudinal links 7 5 are pivoted at their front ends to the chains 64 respectively,

as shown at 76, the rear ends of said links being pivoted at 77 to the receiver frame 59. These links 7 5 and chains 64, when the latter are driven, serveto first rearwardly shift the receiver R to shock-discharging position and to then forwardly return said receiver to its position over the rotary table 32. Thechains 64: however are not driven to efiect'this work, until the drop frame D is lowered as seen in Fig. 2. When this frame descends, the receiver frame 59pulls to some extent upon the,

links 75and the lattercause some idle traveling of the chains 64, as will be seen by comparing Figs. 1 and 2. As soon as the clutch 7 4 is thrown in however, the sprocket 73 and chain .7 2 drive the shaft 71, the latter drives the gearing 70, and said gearing drives the sprockets. 65, thereby operating thev chains Gt and the links.75=' to force the receiver R i'earwardly to shock-discharge position. As

frame D, before the chains 6a have disposed the pivots 76 in front of the sprockets 68. It j thus follows that as the forward movement of the links 75is completed, the frame 59 ofthe receiver thrusts forwardly upon the drop frame D,.thereby moving theilatter forward ly. 'As this frame is thus forwardlym'oved, the hangers and the cranked axle 12cause it to ascend, and by the time thechains 6-l an d' links have moved'the frame D far as v possible, the latch means 25 has come into to hold said frame D. in raised POSltlOIl P y as seen in Fig. 1. The clutch 74 is thendisengaged and the machine isin readiness for theiformation ofanother shock.

' hile any preferredmeans may be employed for limiting the forward travel of the receiver R upon the drop frameD, I have showna stop 7 8 on one of the bars .30 in the path of one of the rollers 58, for this purpose, and it may beconsidered that there is a similar stop at the opposite side of the machine.

A corrugated roller 79is disposed substantially radially at the upper end of the receiver R, the shaft ofjsaid rollerbeing pivoted at 80 to allow the roller to verticallyinove when finishing ashock, asin Patent 1,640,598, above mentioned. his roller 7 9 is driven by gearing 81 from a vertical telescopic 'shaft 82, this 7 shaft being in turn driven by gearing 83 from another telescopic shaft S l, one end of the lat-' ter being driven by a chain 85 and appropri ate sprockets from the shaft 45.1 The chain driven portion of the shaft 84' is carried by standards or the like 86 secured to suitable parts of the main frame M, and saidshaft 84;

embodies appropriate universal joints 87 which, together with telescopic action of the shaft, takes place'when the receivermoves shown).

rearwardly. or forwardly. Other universal joints 88Yare provided in the shaft82 to allow the necessary movement of the latter as the roller 7 9 swings upwardly upon completion of a shock. A-portionof this shaft 82, through the instrumentality' of -a sprocket chain 89 and sprockets, drives a vertical friction-reducing roller 90 at the wall of the receiver. I Y Surrounding the roller 79 and projecting laterally. from the periphery thereof, is an annular knife 91 whose structure is most clearly shown in Figs. 6 to 8. 'As-a shock iscompleted, it is packed and vcrowned. by the. driven roller 79, and the knife 91 severs the crown forming stems or stalks of the grain,

so that the crown may be better shaped and will have less liability to blow off under'the action of wind, than it. would have if the crown-forming stemsor stalks projected.

The knife 91'is formed from a plurality of arcuate sections 92 whose ends overlap eachother and are provided-with lugs 93 fitting between corrugations 94 of the roller "79. Anchoringbolts 95 which lie between the corrugations 94, passv through openings in the lugs 93 andare engaged with appropriate ears-or the-like 96 on one end of the roller 79, This roller is longitudinally tapered and it will be-observed that. the anshoring bolts 95-draw the annular knife 91 toward, the large end oft-said roller,"so that slaidknife is tightly wedged into place. I j

lVhile thegeneral "operation of the machine would probablybe understood from the foregoing, it may bebriefly described as fol:

lows. The machine is connected abreast of and advances with a harvesting machine; (not With the frame D raised as in 1 and the receiver R in its foremost po sition as seen in said view, and with the table 32 rotating, the harvester discharges the cut grain into the receiver and thus a shock is gradually formed in the, latter. When the shock has reached a sufficient height, it is finished ofi' by the crowning roller 7 9, cut

ting off the stems or stalks. of the grain by finished, the operatorv releases the latch means 25, whereupon the drop frame D and the loaded receiver R, immediately move taneously with releasing the latch means 25,

the operator throws in the clutch 74. and, throws outthe' clutch '51. Thus, while mm,

the knife 91, facilitating the finishing opera .tion as aboveexplained. When the shock is downwardly and rearwardly. Aboutsimulti'on of the table 32' is stopped, the chains 64:

are'driven, causing the links ,7 5 to rearwardly slide thereceiver Rfthereby pushing the completed shock'from the table. The gate section 61 clears the shock in the manner above explained. The shock having been dischargechthe chains 64 and links 7 5 function to forwardly movethereceiver Rto the limit allowedby the'stops 7 8-,. and when this.

limit has been reached, the receiver forwardly pushes against the drop frame D, thereby causing upward swinging of the hangers and the cranked axle 12 and again raising the frame D to its normal position. VVhen'it reaches this position, it is held by p the latch means and the machineis then in readinessfor the formation of another shock.

Vhile excellent results may be obtained from the general relation of elements herein disclosed, I'wish it understood that the present showing is for illustrative purposes only and that within the scope of the invention as'claimed, numerous variations and refinements may be made.

In Fig. 5, a modified structure is shown in which the major central portion 12 of the cranked axle is formed by a channel bar, cranked axle ends l2 being connected with the ends of said bar by suitable bearings 12. 12 denotes a reinforcement around the vertical portion ofthe axle end 12 which may be cast in place. 13 denotes a bearing corresponding to'the bearing 18, and it will of course be understood that one of the axle ends 12* is engaged with the bull wheel WV and the other with the wheels W.
